Concept:Hadith No. 3 of al-Nawawi's collection centres on the five pillars upon which Islam is built.
Explanation:Imam al-Nawawi compiled his famous collection of forty-two hadiths to summarise the essential teachings of Islam.
In Hadith No. 3, the Prophet (peace be upon him) stated that Islam is founded on five pillars.
These five pillars are: testifying that there is no god but Allah and that Muhammad is His Messenger, establishing the obligatory prayers, giving zakat, fasting during Ramadan, and performing the Hajj pilgrimage.
Since the entire hadith describes the fundamental structure of the religion itself, its central theme is Islam, not any single act of worship.
The theme of intention belongs to Hadith No. 1, while charity is merely one branch within the five pillars listed here.
Therefore, option C is the correct choice for this JAMB question.
Answer:C. Islam
